How do I calculate defect density per cycle in JIRA?

[sayali patani]

I need to calculate defect density in JIRA. Could anyone please help me with process?

[Heshan Manamperi]

I'm using some back end queries which is more complex. But if this is feasible suing script runner plugin, please try it. 

Normally you can use following calculation for defect density

defect density = (No of defects count) / (No of CR count)

Using this you can have defect density for each project or version/release.

If you have script runner plugin, you can use a scripted field for this. You need to write a JQL based on the filter conditions of cyclle time, status/resolution of issues, parse it and calculate the result. You can also display the result on the master ticket (Epic/Story).
